G35 Owners: I Need Help
So the Slip, VDC, and Parking Brake lights will not turn off in my dad's 05 G35x. It doesn't matter what gear it's in, if you are stopped or moving, or anything.
I've been telling my dad to take it to the shop, but he's been out of town quite a bit recently and hasn't had the chance. I'm no car expert, but maybe a sensor has been knocked loose or something.
Any ideas?

I had this same problem. Tell him to check the level of the brake fluid and if it isn't filled to the max it should be. Nissan's sensor is really really sensitive so it'll through those lights if it's low. If that doesn't work take it to the dealership but this is a pretty known issue on g35driver.

It's most likely the brake fluid low and/or worn pads (which leads to low fluid in the reservoir). I have an M45 and it does the same thing when brake pads are worn. Mine was like that since November and I knew it was my front pads (it did the same thing when my rear pads were worn about 10k miles ago, so I knew it was the fronts and especially since they've been squealing pretty badly), but since it was garaged for the winter anyway I didn't replace my front pads until yesterday...all lights are back to normal.
If it's cold out and pads are slightly worn, it'll come and go out when the brakes heat up or if the weather warms up, but eventually the pads will wear further and it will go on and stay on, so plan on having the pads checked and replaced if worn. If it doesn't go out if pads are replaced or aren't worn and fluid is full, then it could be another problem that needs to be checked by the dealer.

Thank you all for your help! I emailed a link to this thread to my dad so he can check it out instead of me trying to explain it to him.
on the G though.

Like phee said, if this happened in my TL, it would probably be the transmission 
He doesn't drive often, but when he does, the brakes squeak on the rear left side. I guess the car is smarter than we are

Just rear left? I hope both rears are worn. I don't know about the G, but my M's wore out the rears at about 20k miles and the fronts at about 35k...but the rear pads are also thinner than the fronts new. Not sure of the compound though.

My dad bought the car two years ago with 40k miles. Now it's sitting at 54k. Everything was flawless when he bought it, he had a lot of stuff done to it maintenance wise. Maybe it's just time for new pads

One on the right for me
He also gets the lights the OP has. I've pulled the pads, cleaned everything, and flushed the fluid and the lights still appear intermittently

Hopefully ours will be going to the shop soon. Both my dad and I told the guys there that the brakes were squeaking under light braking, but they couldn't replicate it.

on to the next one...
Speed Sensor
if it's not brake related, it's the speed sensor. I had a 2001 Infiniti I30t that had those exact lights on and it was a faulty rear speed sensor.

Is that something that's crucial that should be looked at asap or can it wait a week? My dad drives 8 miles round trip daily

With that said, go with the path of least resistance first - Brake Fluid, Brake Pads, and if that doesn't work, check the sensors...

The light also came on when his clutch was pretty much shot. It didn't made any sense. His car is sort of a mystery. It was totaled a few weeks ago (I don't understand that either since there was hardly any damage) but I guess it is better to be rid of the thing.

Hm. Hopefully it's not the transmission. My dad's is an automatic.

Well, its not an Acura so immediately that reduces the chance of a transmission problem like 90% already
But seriously, as mentioned above, path of least resistance is brake fluid/brake pads. I've already had the lights occur on 2 separate occasions on my car and both times it was the brakes, first rears then fronts. Your fluid being low may be the direct cause of the lights coming on, but i would check the brakes before filling/flushing it since putting on new pads, if they're worn, would bring the fluid level back to normal enough to turn the lights off. And if the brakes are squealing, then that's just another indication it's time for a brake job.

Damn Acura! Sounds like it's time for a well needed trip to the shop.
Thanks again

I don't think the display will light up like an x-mas tree for low brake pads. I can almost guarantee that it's a sensor, probably ABS. 
You could always plug it into an OBD2 reader and it would tell you what's up..

It's not lit up for low pads, it's lit up for low fluid, which is an indication of low pads.
My M did this on 2 separate occasions at around the same mileage that other M owners were reporting having their pads replaced. After my pads were replaced, lights stopped coming on.
This is a common question among infiniti forums and the solution is to check the brake fluid level and/or change pads.

I would like to see you guarantee that it's a sensor...even though from my experience as an infiniti owner and the experiences of many other owners on infiniti forums indicate otherwise.

With that said, check the easy stuff first as Mr. Deeno and I have suggested.
Oh, and I was able to pull that ABS sensor code with my ODBII scanner as well.

Sorry the pictures don't load anymore, went over my damn bandwidth on PB 
Dad finally took the G to the shop this morning. He needed brake fluid and brand new rotors and pads up front. About $600

Was it an infiniti dealer he took it to or an independent shop? Brake jobs are routine (i do mine myself), but dealers charge a crapload for them.

Pricey I know, but it was done by a local trusted mechanic. They work on all 3 of our cars and they are legit, no bullshitters.
My dad had some other things done there as well besides the brake job. He got his oil changed, tires rotated, and a cracking belt replaced. So I guess it wasn't $600 just for the brakes, it was $600 including everything else that was done.

Yea it was pricey, but he had other regular maintenance done as well. The shop is great and I know they wouldn't bullshit us for no reason.

^Hm that's weird.
The place we take our cars to said that Infiniti and other manufacturers program the car to make all of the problem lights come on the dash so it gets the drivers attention quicker, no matter what the problem is.
My dad just needed a brake job, your friend used different tires. I guess that's just the car being smarter than we are
